Read the Amplifier class notes.

For the amplifier circuit shown, R_S = 820 Ω, and R_L = 1.2 Ω.

For amp 1: R_i1 = 560 Ω, A₁= 5, R_o1 = 15 Ω.

For amp 2: R_i2 = 10 Ω, A₂= 10, R_o2 = 12 Ω.

For amp 3: R_i3 = 47 Ω, A₃= 20, R_o3 = 18 Ω.

For amp 4: R_i4 = 10 Ω, A₄= 20, R_o4 = 2.7 Ω.

If the amplitude of the input signal is v_i = 80 mV, find the amplitude of the amplified output singnal, v_o.
